Do you think there are aliens?

[Reenk Roink]

well, only a couple of hundred years ago, a drop in the ocean concerning universal time, we thought it natural to enslave others among our species and to kill off animals bordering to extinction.

Today, all over the world, slavery is frowned upon to say the least, and wild life preservations are all over the place, much funded by the average citizen. We are not born to be good, but generation by generation we are getting closer. Evolve that over some million years...

EDIT: I used these 2 examples as they mimic aliens stumbling upon us, or us stumbling upon aliens. If WE did, do you think we would send nukes, or try to make contact and learn from them?

By the same token, we continue to spend a ton of money on military to ensure/aim for our dominance over the rest of the world. The last 100 years is by far the most violent in our history. Sure it has slowed down because of the superpowers have dwindled to two and later one, but the peace seems only kept as long as the status quo is kept.

There's almost no question in my mind that we'd exploit them BAD if we were stronger.
